Management Notes (for the Swan NRM Region)
Alternative Names. Wild barley, mouse barley.
General Biology. Growth form. Grass. Life form. Annual, caespitose. Reproduction. Seed. Dispersal. Mammals (on fur). Photosynthetic Pathway. C3. Toxicity. Seed can be fatal to lambs, awns on mature plants can cause injury to grazing animals. Seedbank persistence. 2 years.
Notes. Naturalised in North and South America and New Zealand. Dominates other native perennial grasses at high nturient levels. Grows on a range of soil types and tolerates very high nutrient levels. Produces prolific seed. Capable of germinating early and rapidly. Seeds lodge in animal fur/hair/wool and may be transported large distances. Smoke can stimulate seedling emergence. Known to have herbicide resistance.
Additional information. Origin. Europe, northern Africa, western Asia. History of use/introduction. Contaminated seed, hay and wool.
Suggested method of management and control. Prevent seed set. Hand pull or spray with Fusilade® Forte 16 ml/10 L or 800 mL/ha (based on 500 L water/ha) + wetting agent or for generic fluazifop-p (212g/L active ingredient) 10ml/10L or 500ml/ha + wetting agent 4-6 weeks after opening rains. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
